Question: What portions of the image were missing from Facsimile 1?

Examination of the extant papyri fragments reveals that portions of Facsimile 1 (the only facsimile that survived) are damaged

For a number of years, scholars have debated whether the facsimile was damaged before or after Joseph acquired the papyri. It seems that the Book of Breathings scroll (containing Facsimile 1) was marred by a lacuna—a missing portion—that had torn off the scroll. The debate over the date of the lacuna directly relates to the images on Facsimile 1. This vignette—as shown in the LDS Book of Abraham—shows a figure (interpreted as Abraham) lying on a lion couch with arms raised as if attitude of pleading or prayer. The figure standing over Abraham is a bald man (presumably an Egyptian priest) with a knife in one hand—as if he was about to kill Abraham. Flying just above Abraham is a hawk (or falcon) with outstretched wings. The scroll's lacuna extends over an area which includes the Egyptian priest's head, the knife, and one of Abraham's supplicating arms.

This photo of a lion couch scene was taken at the Louvre. Note the mummy-like appearance of the figure on the couch. The two legs are wrapped, unlike those of the figure in Facsimile 1. Also note that there is only one bird.

In the penciled in restoration, the knife is in the priest's right hand, and the face is viewed from the front.
